I have two ReadyNas (Ultra 4 and Ultra Pro 4). My drives are currently full so i was planning to wait in december until WD releases the 5TB red. I was just wondering if the 5tb drives will work out...

Aug 30, 2013thanks to both of you for those explanations, i understand now :)
The only part i don't understand is:
If i understand correctly, cloning is only used when 2 drives fails and it will result in some data corruption. If only 1 drive fail, there will be no data corruption ?
A long time ago i replaced 2 of the drives in my NAS at same time (i assumed it was the 2 backup drives because i was thinking the drives were 50% files 50% backups) and i noticed some movies were impossible to read after that. I guess that's why.
The only part i don't understand is:
BTW, one consequence of cloning is that the NAS thinks all the blocks on the cloned drive are correct. Since that is not really the case (some of the original blocks couldn't be read), it will result in some data corruption.
